The digestibility of roots with ruminants cannot be determined 

 by feeding a ration composed of them alone. It is necessary, 

 therefore, to feed with them some fodder material like hay, straw, 

 etc. The roots, the digestion coefficients of which have been 

 ascertained by feeding trials during 1890 and 1891, are sugar 

 beets, mangolds, rutabagas and English flat turnips. With these 

 were fed a known quantity of Timothy hay (No. CXL), the 

 digestibility of which had been previously determined. In order 

 to test the four varieties of roots mentioned, it was necessary to 

 employ four animals during two periods.
